IMPROVEMENT IN ROCKING-CHAIRS.

Specification forming part of Letters Patent No. 116,689, dated July 4, 1571.

To all whom it may concern:

Be it known that I, GEORGE Gsnrr, of the city, county,a1'1d State of New York, have invented a new and Improved RockingUhair, and that the following is a full and exact description of the same, reference being had to the accompal nying drawing and to the letters of reference marked thereon makinga part of this specification.

The object of this invention to construct a rocking-chair in such a manner as will admit of a rocking motion without moving the pedestal or support, which will therefore remain in a fixed position on the floor. The invention consists ot' a pedestal having casters which will sink into recessed legs when the chair is in use, the legs then resting on the i'loor, but which will allow of the chair being rolled over the iioor when not in use. Also, of a peculiarlyeonstructed rocking mechanism by which the chair-seat only moves, the pedestal remaining on the iioor without bein gnecessarily moved.

In the accompanying drawing, Figure 1 is a bottom view ofthe pedestal of my chair, and Fig. 2 a side view of chair and pedestal partly in section.

Similar letters of reference indicate like parts in the severa-l figures.

A represents a rocking-chair, the back, arms, and seat of which may beoi' the ordinary construction, and of any desired form. The lower part B Oi' the chair, instead of being' secured to the Ordinary rockers, is attached to pivoted levers c. These levers are constructed of metal, and inclosed within the pedestal D, as shown in Fig. 2. At a middle point between the ends al a of the lever C, on its lower side, is secured a pivot, p, made in the shape of a knife-edge or balance-center, and pivoted on the step or projection e. Secured to the upper sides of the arms c c of the levers C are the rubber or other elastic springs e e ,the upper end of said springs cushioning aga-inst the projections ff ofthe pedestal.

(See Fig. 2.) Now it willbe observed that, when the cha-ir A is secured to the levers C by means of the dovetailed tongue g, (as shown in Fig. 2,) or otherwise, a very slight movement ofthe person occupying the chair will cause the levers O to oscillate onA the pivot p backward and forward, at pleasure, as in an ordinary rocking'- chair, the movement being facilitated by the action of the springs e c in a manner which is obvious. lf the pedestal l) were itted with casters in the ')rdinary manner, it would be plain that the rocking motion ot' the chair would cause the pedestal to move about the room and abrade the earpet. To obviate this difficulty, I attach the casters h tothe end oi' springs i, the other end of said springs being secured to the pedestal iu any desired manner, so that when the chair is unoccupied the casters are exposed and free to act; but when the chair is occupied by the person using the same the casters will be forced upward and be received into the projection j of the pedestal l), bringing the under surface of the pedestal in contact with the floor, and thus holding it iirmly in position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The pedestal D, provided with legs j j, in which c: sters h h. attached to springs i i are secured, when the said legs and springcasters operate in connection with the rocking mechanism and seat, as and for the purpose specified.

2. The chair B, mounted, by means of the tongue g and socket, on. the levers C, oscillating lon a pivot, p, which rests in the socket c, and

rendered elastic in their movement by springs e, in combination with the pedestal and its parts, thewhole constructed and arranged substantially as set forth.
